I recently changed my 2015 Harley FLHXS to amsoil in all 3 holes. It's cooler weather now so I can't really tell if the engine is running cooler as others have said. I can attest that my transmission shifts better and less clunking when dropping into 1st gear. Either the bike is happier with the amsoil granny lube or the amsoil primary lube. Either way I am very happy with the amsoil products for my bike. Is it possible that lubrication change makes it feel easier to back the bike up? Doesn't make sense but it sure feels easier to back up.
Bottom Line
Yes, I would recommend this to a friend.

Works great in my ‘08 Road King. Probably change fluid before I actually need to but it has become a yearly habit.
I read a lot about how Amsoil would quite down the changing of gears as well as make it much easier to find Neutral.... LET ME ASSURE YOU ITS TRUE.
I am shocked it worked as well and it did.
I use only the best in my vehicles, V-Twin synthetic works great on my Streetglide. I use Amsoil in both my trucks and my wife's SUV. Never have internal engine problems. Thats a 02 and 08 trucks and a 2011 SUV. Cant go wrong with Amsoil.
